Back 1

mouth, vagina


**on practical

Front 2

Connective Tissue (Second main type) Characteristics

Back 2

opposite of ET

Abundant intercellular matrix with few cells

Wide range of vascularity (blood vessels)

Front 3

Name the 4 subtypes of CT

Back 3

Connective Tissue Proper

Osseous
Vascular CT / Blood

**On practical

Front 4

Name the 3 components of CT

Back 4

1. Ground Substance
2. Fibers
a. Ground substance + fibers make up the matrix
3. Cells

Front 5

Name the 3 types of fibers of CT

Back 5

Collagenous fibers - thick and pink
Elastic Fibers - Yellow and dark
Reticular Fibers - jagged in appearance

Front 6

Name the 2 different fiber arrangements in CT

Back 6

Loose fiber arrangement - few fibers and many cells
Dense fiber arrangement - many fibers and few cells

Front 7

Name the 4 types of cells found in CT Proper

Back 7

1. Fibroblasts - make fibers (does all work in CT)
2. Mast Cells - Produce histamine (allergies) and heparin (inflammation)
3. Mesenchymal Cells - undifferentiated (stem cell, present at birth)
4. Macrophages - phagocytic (lymphocyte)
Other cell types in CT: Osteoblasts/osteocytes, chondroblasts/chrondrocytes, erythrocytes, leukocytes, thrombocytes

**on practical

Front 8

matrix

Back 8

liquid called plasma.
Semisolid
Possess lacunae

Front 9

Name the 3 blood cell types

Back 9

1. erythrocytes (RBC)
2. leukocytes (WBC)
3. thrombocytes (Platelets)

Front 10

erythrocytes

Back 10

(RBC)
Anucleated and biconcave
Carry respiratory gasses (O2 and CO2)

Front 11

leukocytes

Back 11

(WBC)
Nucleated
Fight microorganisms

Front 12

thrombocytes

Back 12

(Platelets)
cell fragments - appear as tiny purple dots
Function in clotting

Front 13

chondrocytes

Back 13

(cartilage cells)
lacunae are small chambers where chondrocytes are housed

Front 14

name the collagenous fibers in the matrix in compact bone

Back 14

1. Osteon (haversian system)
2. Central Canal (Haversian canal)
3. Lamellae - concentric rings of matrix
4. Lacunae - (little chambers) houses osteocytes
5. Canaliculi - small canals (with cytoplasmic extensions) that connect lacunae (osteocytes)
